State of Zarr V3 and ZEP0001

The Zarr community is working on a new version of Zarr, V3, which was drafted and proposed via ZEP0001 by Alistair Miles. Due to time constraints, we, Jonathan Striebel and Jeremy Maitin-Shepard, are taking over the lead authorship of the V3 proposal.

The specification is now being finalized and needs your feedback before the Zarr Steering Council and the Zarr Implementation Council vote on it. In two weeks, (on the 19th of December), the spec will go into feature-freeze, meaning only changes (issues) that have been previously discussed will be incorporated. The documents in question are:

• Zarr Enhancement Proposal for V3 (ZEP0001)

  Motivation and Context

• Current draft of the V3 Specification

  The Actual Spec

If you are familiar with V2, you might want to start at the comparison with V2 section of the specs.

Please feel free to:

• Add to the current discussions in issues on the project board,
• Open pull requests for changes, or
• Add new issues if your topic does not fit any existing ones.
